The (light emitting diode) 10 is a notification unit for notifying an incoming call. For example, the speaker 8 notifies by a sound, the vibrator 9 notifies by vibration, and the LED 10 notifies by a lighting or blinking. Which means is used to notify the incoming call can be arbitrarily set by the user.

The display section 11 is composed of a liquid crystal display panel having a display capacity of, for example, about 20 digits × 2 rows, and its drive circuit. The display section 11 displays selected message data to confirm the contents. The key input unit 12 includes various keys for calling and displaying the received message on the display unit 11 and for instructing the operation of the pager.

B. First Operation Example of Embodiment Next, an operation of the pager according to the above-described embodiment will be described. Here, FIG. 2 is a flowchart for explaining the operation on the transmitting side, and FIG. 3 is a flowchart on the receiving side (pager).
5 is a flowchart for explaining the operation of FIG. Also,
FIG. 4 is a conceptual diagram showing a display example of a pager.

(1) Operation on the transmitting side (center side) First, on the transmitting side, in step S10, a user sends a message to a message receiver of a predetermined call number in a divided manner (hereinafter referred to as a divided random message). ) Is registered, in step S12, the registered divided random messages are rearranged one by one (per division unit) in random order and stored. In addition, it is not necessary to rearrange in a random order. Next, step S14
Then, it is determined whether or not a normal message has been registered with respect to the call number for sending the above-mentioned divided random message, and the process stands by until the registration.

When a normal message is registered,
Proceeding to step S16, one character of the randomly divided divided random message is attached to the normal message. At this time, an identification code (separation code) is inserted between the normal message and the character attached to the divided random message in order to distinguish the normal message from the divided random message.

Next, in step S18, it is determined whether or not the character attached to the normal message is the first character.
In the case of the first character, in step S20, information (the number of divisions) indicating how many characters the divided random message is composed is attached after the attached divided random message. On the other hand, if it is not the first character, the process proceeds to step S22. In step S22, the normal message and the divided random message (in the case of the first character, the number of divisions in addition to this) are transmitted to the pager.

(2) Operation of Receiving Side (Pager) When the power is turned on, the receiving side pager waits for an incoming call in step S30, and determines in step S32 whether there is an incoming call (step S32). Judge if the message is addressed to you). If there is no incoming call, the incoming call waiting state is continued. On the other hand, if there is an incoming call, the received message is stored in a predetermined area of the RAM 6 (Step S).
33). Thereby, a plurality of received messages are sequentially stored. Then, the process proceeds to step S34, where it is determined whether or not a divided random message is added (it is determined whether or not there is an identification code in the message). If the divided random message is not added, step S42 is performed.
Then, the received message is displayed, and a standby state (incoming call waiting state) S30 is set. On the other hand, if the divided random message is added, the stored received message is separated into a normal message part and a divided random message part (step S35), and the process proceeds to step S36, where the added divided random message is the first character. Is determined. If it is the first character, in step S38,
At this time, after storing the number of divisions added to the message, the process proceeds to step S40. On the other hand, if it is not the first character, the process directly proceeds to step S40. The divided random messages are sequentially stored in a divided random message storage area in the RAM 6. The divided random message storage area is stored with at least the number of divisions and the configuration of the received message. Further, a plurality of divided random messages may be stored in the divided random message storage area.

In step S40, since one character of the divided random message has been received at this stage, the number of divisions is subtracted by one. In step S42, the received normal message and the received characters of the divided random message are displayed on the display unit 11 separately. For example, in the example shown in FIG. 4, at the first reception, as shown in FIG.
A normal message "Call Miyuki" is displayed, and the character of the divided random message "K" is displayed. At this time, based on the number of divisions,
The number of the displayed character is represented by a fraction (in this case, 1/3: the first character of all three characters). Then, the received character of the divided random message and the normal message are separately stored.

Next, in step S44, the number of divisions is "0".
Is determined. If the number of divisions is not "0",
Since characters constituting the divided random message are still transmitted, the process returns to step S32 and waits for the next incoming call. Hereinafter, steps S32 to S44 will be described with the number of divisions being “0”
Is repeated until each time, the normal message and the transmission character of the divided random message are received and stored, respectively. For example, in the second reception, FIG.
As shown in (b), a normal message of "Yasuo is late" is displayed, and characters of a divided random message of "!" Are displayed. Then, at the third reception, as shown in FIG. 4 (c), a normal message of "answering machine" is displayed and a character of a divided random message of "su" is displayed.

On the other hand, if the number of divisions is "0", that is, if all the characters of the divided random message have been received, the process proceeds to step S46, where the display unit 11 displays that all the divided random messages have been received. . Here, the user selects rearrangement of the divided random messages. When sorting is selected by the user, step S
At 48, the divided random message is read and the display unit 1
1 and rearranged according to the user's instruction. After rearranging the messages using the keys of the key input unit 12 or the like, the user instructs whether to save them as a divided random message or a normal message. In the example shown in FIG. 4, the divided random message is “ki”,
Since "!" And "su", for example, "su", "ki",
By rearranging it as "!", The message becomes "Like!"

Next, in step S50, it is determined whether the rearranged message is to be stored as a divided random message or a normal message. If a normal message is specified, in step S52, the message is stored as a normal message. . On the other hand, when a divided random message is instructed, in step S54, it is stored as it is as a divided random message. Step S52, S5
When the storage in step 4 is completed, the process returns to step S32 and waits for the next incoming call.

As described above, in the present embodiment, by dividing a message and transmitting it at random, an effect is obtained that the contents of the message cannot be known until the received messages are rearranged in the correct order. In the first operation example described above, a correct message is created by rearranging the characters of the received divided random message by the user on the receiving side. However, the present invention is not limited to this. When transmitting the next normal message, the original message before the division may be transmitted. Further, in the above-described first operation example, the message is divided and transmitted one character at a time. However, the present invention is not limited to this, and the message may be divided in a predetermined unit. Furthermore, without being limited to characters, pictograms and illustrations may be divided and transmitted. If the sender can be specified on the center side, the specified sender may be added. In this case, it can be easily recognized that a divided random message has arrived from a specific sender, and an unpleasant message can be prevented.

C. Second Operation Example of Example Next, a second operation example according to the present embodiment will be described.
In the first operation example described above, the character information is divided and transmitted at random. In the second operation example, the program executable by the pager is divided and transmitted at random, and the divided programs received by the pager are combined. , To be executed. Examples of the program include a program for rewriting the contents of the ID-ROM 4 and a program replacing the program of the ROM 5. Hereinafter, the operation will be described in detail.

FIG. 5 is a flowchart for explaining a second operation example of the pager. First, the transmitting side (for example, a base station) divides a program to be transmitted to a pager into predetermined units, and, according to a data format to be transmitted to the pager, uses the message fragment number to divide the divided program into the same as in the first operation example. , As a split message.

When the power is turned on, the pager on the receiving side waits for an incoming call in step S60, and determines whether there is an incoming call in step S62. If there is no incoming call, the incoming call waiting state is continued. On the other hand, if there is an incoming call, the received message is saved (step S6).
3) The process proceeds to step S64, and it is determined whether a division program is added. If the division program has not been added, the process proceeds to step S66, and the received message is displayed on the display unit 11.

On the other hand, when the division program is added, the division program is divided from the received message (step S67), and a normal message is displayed (step S68). Then, the process proceeds to a step S69, and it is determined whether or not all the programs have been received. Completion of reception of all programs is determined by resetting the message continuation fragment to “0”. In other words, the pager receives the received long message as being (part of) the split program until the message continuation fragment is reset to "0". If all programs have not been received, the process returns to step S62 and waits for the next incoming call. Hereinafter, steps S62 to S68 are repeatedly executed until the message continuation fragment is reset to “0”, and each time the division program is received and stored.

When the message continuation fragment is reset to "0", it is determined that all the programs have been received, and the process proceeds to step S70 to synthesize the stored divided programs. (Program name, date and time of reception, function, etc.) are displayed on the display unit 11. Next, in step S74, the CP
The above program is executed by U7.

In the above-described second operation example, by dividing the executable program and transmitting the divided program, the information of the pager can be rewritten wirelessly, and a new function can be added. can get. In the above-described embodiment, the present invention is applied to the pager system. However, the present invention is not limited to this. Of course, the present invention can be applied to any system that transmits a message (for example, a short mail of a mobile phone, an electronic mail system, etc.) is there.
